Objective: Recent evidence suggests that adiponectin may play a role in bone metabolism. Previous studies demonstrated that the adiponectin levels had a negative correlation with bone mineral density (BMD) in women. However, little is known about the relationship between adiponectin and BMD in men. The aim of this study was to determinate the relationship between the adiponectin levels and BMD in elderly men. Design: Cross-sectional study including 92 healthy men aged 60-80 years. Methods: Main outcome measures were the adiponectin levels estimated by RIA and BMD at lumbar spine and femoral neck using dual energy X-ray absorptiometry. Results: The negative correlation between adiponectin and BMD at the spine was rZK0.209, (P!0.05) and at the femoral neck was rZK0.237, (P!0.001). These correlations disappeared after adjustment for body mass index (BMI). When stratified by BMI, the relationship between BMD and adiponectin remained significant in the subgroup of participants with BMI O27 kg/m 2 , but disappeared in men with BMI %27 kg/m 2 . In multiple regression analysis, adiponectin was a significant determinant of BMD at the spine, not at the femoral neck, in those with BMI O27. Conclusion: BMD is negatively associated with the adiponectin levels in men older than 60 years and this relationship is greater in those men with BMI O27, which suggests a plausible connection between bone and fat tissue.
GDM is not associated with OC, ucOC, OPN, and leptin and does not correlate with insulin resistance. At postpartum, women who develop diabetes have lower osteocalcin concentrations. Leptin correlates with insulin resistance and bone biomarkers in non-diabetic women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
